Anyone have an A1200 "Power Tower"

I think all the 040 accelerators for the A1200 take 72-pin SIMMs, which are easy enough to find second-hand. Which 1240 specifically do you have? e.g., a Blizzard or something else? Some accelerators require certain physical characteristics for their memory--for example, I recall that Blizzard 1240/1260 boards need single-sided SIMMs; if there are chips on both sides it won't fit in the slot.

That should be a pretty zippy system once you get some RAM onboard!

Those are "Z4" slots from one of these Zorro busboards - not related to the accelerator RAM.
It's hard to tell, but I think the accelerator is an Apollo - have a look at the pictures on the two hardware databases and compare. If that's the case, it looks like you'll want a single-sided 32MB SIMM, or two of them if the board has a second slot.
